A. Cover Letter:
1. No comments.
B. Application Fee:
1. No comments.
C. Distribution of Class A Residuals (FORM: DCAR 06-16) Application:
1. The responses to application items III.4, and IV.3. through IV.6. all state "Source Specific" because
of the difference between the operating procedures for the composting program and the water
treatment plant distribution program. These items shall be addressed individually for each program
in an updated DCAR form.
2. Application item IV.2. is to be completed if residuals are to be mixed with other materials. The
composting program would meet this requirement. This item shall be completed in an updated
DCAR form.
D. Operation and Maintenance Plan (O&M Plan):
The submitted Operations and Maintenance Plan appears to only address the O&M relevant to the
land application of water treatment plant residuals by the land application contractor, describing
bulk land application activities of liquid residuals. This does not address O&M requirements for
the composting equipment and processes described in the cover page of the permit, which is
functionally a separate Class A program that is covered under this same permit. A separate O&M
Plan shall be provided for the composting program meeting the requirements of 15A NCAC 02T
.1110.
E. Residuals Source Certification (FORM: RSC 06-16) Form:
The RSC Summary form lists that the South Burlington WWTP (previously listed as the Southside
WWTP) is being renewed for 2,700 dry tons per year (DT/yr). The previous permit's Attachment
A stated that the maximum DT/yr from the Southside WWTP residuals generating facility was 450
DT/yr, while the maximum DT/yr of compost that can be distributed is 2,250 DT/yr. However, the
compost maximum DT/yr includes both the 450 DT/yr from the Southside WWTP and amendments
added in the composting process (i.e. there is 1,800 DT/yr of amendment material included in this
value). The RSC Summary form shall be updated to provide separate maximum DT/yr values for
the South Burlington WWTP residuals generating facility and compost to be distributed. If these
values exceed what was in the previous permit, a permit major modification shall be made with the
associated fee. Additionally, the quantitative justification shall be updated if needed based on any
changes.
2. On page 7 of 31 of the lab results from the American Testing Technologies' February 24, 2022
TCLP report, there is a pH result for the "# 1 Digester Land App" that is 12.75, which is considered
a corrosive hazardous waste under the Resource Conservation and Recovery Act (RCRA). Please
provide an updated sample of this residuals source generator material to verify that it is not a
hazardous waste.
